Driven by org-mode. I still would like to generate the plots statically and link them into the text and do html... and there are zillion other tests to run, but the highlights are: WIRED TXQUEUELEN=1000 BANDWIDTH=100Mbit BQL=4500 (byte queue limits) 1 iPerf induces 10-12ms latency w/pfifo_fast 10 iPerfs induces ~107 ms latency w/pfifo fast 10 IPerfs induces ~2.8 ms latency w/sfq 10 iPerfs induces ~1.7 ms latency with staqfq
